Also, the B&O has color position light signals - same arrangement as the
PRR's but no center light, and red, amber and green lenses.  Also, the
Pennsy converted most position light signals to amber lenses - at least
I've not seen any lunar white lenses lately.

The former Alton lines of the GM&O (now ICG) have color position light signals,
which is explained by B&O's ownership of the Alton for many years.

I see that on the few remaining ex-Pennsy lines here in Illinois, Conrail has
replaced the position light signals with NYC-style color light signals.  Is
this happening elsewhere?
